Unlocked D850, no 3G or LTE



Hey guys, just wanted to say that I've already searched endlessly on this before making this post, appears to be a somewhat common problem but any solutions are few and far between.

I have an unlocked D850 that I am trying to use overseas (Personal, in Argentina). My phone is indeed unlocked, as GSM and Edge networks work without a problem. My phone is not receiving any 3G or LTE service. I have a D851 with identical APN settings sitting right next to it showing full bars of LTE, so I know that is not the problem. My carrier here uses 850/1900 for 3G and 1700 and 700 for LTE, the phone should be compatible with all these bands.

I have tried switching to Cloudy 2.5, CM12, and other roms, no luck. I have tried the intelli3G trick posted in another thread, no luck. I have tried purchasing another unlock code from a different service provider, no luck, the phone says its already unlocked. I have tried changing the bands in the service menu, but the phone does nothing, and forcing the phone to LTE only in CM and stock based roms, and the phone loses signal completely. I haven't tried switching to a different radio/modem, but I'd be willing to try.

Does anyone else have any suggestion or recommendation for me, I'd be able to provide screenshots and logcats, but please don't tell me that I spent several hundred dollars for a phone that can't even stream music without stuttering. Thank you for looking
